VALVE FOR GAS-BURNERS.

i `Specification of Letters Patent No. 12,515, dated March 13, 1855.

Be it `known that I, ANDREW MATER, of

. the city 1 and county of Philadelphia and `State of Pennsylvania, `have invented a new` and usefulmprovement in Gras-Burners;` and I do hereby declare that thefollowing is a" full, clear, and eXact description of the same, reference being had to the accompanying drawings,`forming a part of this specification, `in which- Figure lis an outside view of a` gas burner, having my improvement applied. Fig 2 isa longitudinal section of the same i taken through the center. Fig. 3 is a transverse section `of the same in the line a1, y, of

" through thecenter of the regulating valve Fig. 4 is `a Vlongitudinal section box. l

Similar letters `of reference indicate corresponding parts in the several figures.

` This invention relatesto `the Inode of arranging and tting the regulating valves which are applied to gas "burners to regulate Vwthe flow and consumption. of the gas.

` "Owing to the minuteness and delicacy of` thesevalves, ithas always been difficult to apply them to the burner in such a way as l to have their perfectoperation insured, but `this invention entirely overcomes this diiii culty.

To enablethose skilled inthe arttomake and use my invention, I will proceed `to describel its construction and` operation.

l c; a, are the valvesfarid b, the cups y whichV receive them, all of the usual cony struction. `These valves andcups are comy monly placed one by one, in the lower part `of the burner, the cups being surrounded *by "white lead, to` make them fit the burner i i with perfectly tight joints.` Owingto the i Y distancethecups have" to be `inserted in the burner and the consequent difliculty of hand` i ling them itis almostimpossible' to prevent someof the white lead, gettinginside `the cups or being so spreadas to get between thevalves andtheir seatsin the cups. The

i and valves inthe burner itse`lf,I place theml in a boX orshort tube c see Figs. 2,3 and `4,

which is of suitable size to receive them. Into this tube they can be conveniently `inserted as there is no difficulty in handling them, and owing to the facility for insert-ing the cups in their proper position an eX- tremely small quantity of. white @lead is necessary to make the joint around them, so little that there is no danger of its getting beyond the sides of the cup.l lVhen the cups are in the tube, they are expanded to lill the tube tightly by inserting a punch in them. I Y

The tube c, is not `placed in the burner itself but in a small chamber A, which is placed below the burner B and is inserted with a small quantity of white lead to keep it tight, but this whitelead is in no danger of coming in contact with the valves or their seats. This chamber is made of brass or some metal that is not so liable to oxidation as the metal, viz steel or iron,V of which the burners are made, it is made with a male screw at the top to fit the female screw in the ordinaryburner and with a female screw at the bottom similar to that inthe ordinary burner, and as it is customary in the trade to make all the burners with a screw of uniform size and pitch the chamber containing the regulating valves may be applied to any burner in a minute by taking olf the burner and screwing the chamber `in its place. The chamber is made with holes in the top similarly arranged to those which cause the spread' of the 'flame in an ordinary gas `burner in order to spread the gas inthe lower part of the burner and prevent it blowing upA through the burner in a direct strea `What I `claim as my invention and desire to secure by Letters Patent, is-

` Fitting the valve cups b, b, to a tube C which forms a valve-box, in which all the cups and valves can be properly fitted without diiculty, and inserted conveniently in theirplace in the burner, or into any cham- 4ber prepared to receive them, as herein fully S. P. RAWLE.
